Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40280, here are decompositions:

3 + 40277 = 40280
43 + 40237 = 40280
67 + 40213 = 40280
103 + 40177 = 40280
127 + 40153 = 40280
151 + 40129 = 40280
157 + 40123 = 40280
181 + 40099 = 40280

Showing the first eight; more decompositions exist.
